To all whom it ma /y con/eerie;

' Be it known that l, PETE}; F. Lyons, of Boston, in-the county ofSufi'olk and State of Massachusetts, have invented certain newand-useful Im rovem'ents in" Flexible Connections for eter-Closetsandthe Like, of which the following is u specification This. inventionrelates to' wetcrcloset bowls and the like, and has for its object to'10 provide such a bowl with a union capable of Joining the outlet ipeof the bowl, which is made of inelastic, )rittle'material, as prircelain, etc., with a ri-gidly mounted pipe of tough material, such asiron, which will be yielding'and flexible to permit of relative movementbetween-the parts without breakage of the brittle material.

It frequently happens that when it closet bowl'is set upand connected totlw'soil-pipe,

. 20, it is eithernotsquarely setpn its support, or

the pipe to which it is connected may run at such wrangle that when thebowl is securely coupled thereto a portion oiyit is slightly raised fromits support, or the support may not'be sufliciently rigid, or from someother cause-the bowl may be sopositioned that .whensubjected, topressure under the ordina conditions of use, it is caused to move sligtly relatively. to the pipe, to which it connected, with the immediateresult of the portion of the outlet projection t e metaltpipe to crackor break ,ofi

- 'rt, producing a leak, tofre nedy which a .jne'w 'bowiinustbesubstituted at; a cost of 5 some expenseandfmor e inbonvenienee.

The reference letter 0, represents an ordi narywater-closet bowl having,an integral o\.\tli' t-pipe or tubular stern Z made of porcelain orsii'nilnr unyielding, brittle material.

it is the soil outlet-pipe leading, to the plumbing system of the.building, which is usually of metal and unyiclrlingly positioned, and cis the connection between the two.

This (.o'nncotion, us most clearly seen in. Fig. 6 5

3, consists of a metal member having a flange e which bolted to theiliinge f of the soilpipc, an elastic gasket h being, interposed between the two to make a wet-erand gastight joint, and a screw-threadedtubular 7o portion g'adapted to extend over the end of. the outlet (1,its internal. diameter being eonsiderabl greater than the externaldiameter of the outlets.

Between the outlet 1; and tulmlar part 9 is interposed n pecking-ring iof rubber or-other elastidor yielding conuiosition end 011 the outsideof the part 5: is screwed a threaded annu'lar'nut it which has animvardly-projecting flange Z extending over the space oocupied, by thepackingqing end constituting the gland of t pecking. A metal ring y' ofa diameter entithiekness such es to permit it to enter the space betweenthe tubular part 9 oi the connection and the outlet i) looselysurrounding the letter, is interposed between the packing-ring and theflange Z. The memher 0 also has aninternal flange or shoulder 6extending inwardly to cover the space occupied by packing and which maextend also fever the end of the outlet 5, t 1e whole constituting aconnection which may be handied separately and maybe slippedover theoutlet projectionoi any bowl. After" being so placed it may be securelyfastened Infup the annular not, which forcesthe ring or gland; againstthe elestic )acki1ig-- utter and causing i't/tobind against the innersurface of the tubular projection and the'exterior of the outlet]; withnt by which the nut is -screwe up. The connection'is usually locatedbelow the normal leve'i of .tl 1e Water in the a. para,-

tus', indicated by the dotted line in' igs l and 3, in order that incase the joint should i not be made tightenough, an leak emay reme,ed'by,

twill eobse-rved that this structure provides a connection which willpreventflany leakage and which yet be-sufiiciently i ro yielding topermit some fiexion lmtween the )owl and the soil-pipe. When the partsare connected a space is left between thecnd of the outlet 11 and theflange c to allow for enough yielding to compensate for whateverinaccuracy is ordinarily likely to occur in setting up the bowl in thefirst place or whatever distortion may take place later.

I do not limit myself to the exact details described, as minor changesmay be made Without departing from the spirit of the invention, orto theparticular use in connection with which the device has been hereinbeforedescribed, since such a flexible coupling is adapted to be employed inany relation in which two pipes are required to be joined flexibly andyet tightly.

I 1. 'lhecombinationwithaclosetbowlhaving an integral tubular outletstem above the base of the bowl and below the normal level of watertherein, and a metallic outlet pipe, of a connection havinge flange for,rigid at taohment with a similar flange on the pipe and provisions formaking a flexible w atertight connection with the outlet stein; saidprovisions cor'isisting, of a tubular member or flange surrounding thestcn' an internal shoulder within said tubular flange, an elasticPacking betweensaid flange, shoulder and. stem, and a gland threaded onthe flange-outside of the stem adapted to compress the elastic packingagainst the flange and shoulder and thereby cause it to press tightlyand yieldingly against the outlet stem.

2. The combinationof a closet bowl having an integral tubular outletstem free from external projections; a metallic pipe abuttin saidoutletstem; and a yielding watertig t connection unitingsaid pipe andstem located abovethe base of thebowland below the normal. level ofwater in the bowl, comprising a member having; a flat annular flangeconnected to the metallic pi e, a tubular ex tension surrounding theend' of the stem, an internal annular shoulder projecting across the endof tl\e-stem and separated therefrom;

r anelastic packin contained-between said tu- 7 bular member, t e stemand the shoulder; a.

nut threaded on the exteriorof said tubular member and formed with-aflange projecting over the end of said tubular member and der, and anelastic annular packing rin loosely surrounding said stem; and a rigidcompression ring located between the stem, packing and nut and whollyinclosed thereby.

3. The combination of a closet bowl having an integral laterally andupwardly projectingtubular outlet stem free from external projections; ametallic continuation of said stem an extendinglaterally away therefrom;a lateral flange formed on the end of the metallic ipe; and a yield ingwater-tight connection between said pi e and said stem located above thebase of tlie bowl and below the normal level of Water in said bowl,comprising a tubular member provided with a lateral flange connected tothe gipe forming a flange of the pipe and surrounding the end of thestem, having an internal annular shoulder projecting across the end ofthe stem and separated therefrom; an elastic packing con- .tainedbetween said tubular member, the

stem and the shoulder; a nut threaded on the exterior of said tubularmember and formed l with a flange projecting'oVer the end ofsaid tubularmember and loosely surround'ing 'said stem; and a rigid compression 15mglocated between the stem packing and. nut and wholly inclosed there y.

4. An attachment for closet howlsand the like'comprisi'ng a flatannular'plate or ring its external and internal diameters anexternally-threaded annular rib; or tubular memher, the portion of theplate external to said rib or member constituting a flangohavihg.

having extending from oneside intermediate provisions for attachment toa complemen-. tal abutment, and the internal portion con-- stituting apacking. shoulder, a nuti or ring mounted externally on the tubularmember in screw threaded engagement therewith and formed with aninternal flangenforming a shoulder in line with the said packingshoulcontained within .the' tubular member an said shoulders andarranged to be oompressed and distorted by adjustment toward each otherof said shoulders. s
